Wen gluing frags to rock work, not every place to glue a frag is horizontal. This one crom time to time needs to glue frags to the side of rock work. I assume if I take an acro and glue it pointing sideways on the side of my rock work, it will grow towards the light. Correct? Also, many corals have different growth patterns. Are there some that will not grow right if not top mounted on a horizontal piece of rock?
